What is a Rotary Encoder?

A rotary encoder is a sensor that can detect the angle, rotation speed, and rotation direction of a rotating shaft.

• The encoder accurately reads the position and synchronizes the operation precisely with other devices.
  For example, by synchronizing the timing of transfer and processing machines, smooth process management becomes possible.
• By detecting abnormal rotation speeds, machine failure and workpiece jams can be detected early on.
• Application Example
  By comparing the controller output pulses with the encoder detection pulses, can be quickly detected stoppages caused by foreign objects or other issues

Small, Thin, and Lightweight Magnetic Incremental Encoders

A wide variety of product lineup includes two types of frame sizes (Ø30 mm/Ø40 mm), three output circuit types with line driver, voltage, and open collector (power supply voltage 5-24 VDC), and 14 resolution types with 100-4000 P/R. 

The actual position, speed, and rotation direction of conveyors, belts, pulleys, and other mechanisms can be detected. This contributes in the construction of predictive maintenance systems.

Easy to Aligning the Mechanical Home and Z-phase Signal

The Z-phase signal is output once per revolution when the encoder connector section is facing down and the shaft flat section (round shaft type) or fixing screw section (hollow shaft type) is in the position indicated by the red arrow.
